So will Kate end up as Senator Beckett and have three kids with Castle?

Change isn’t always easy and no one knows that more than Castle.

Even though “Flashdance” star Jennifer Beals will be guest-starring in the next two episodes, don’t expect any one shoulder sweatshirts, leg warmers, or dancing montages on “Castle.” And instead of water pouring down from the ceiling, there’s a body that falls from a fourth storey window.

In the episode, “Pandora,” airing on February 13th, the former “Flashdance” actress stars as Sophia Turner, a CIA operative from Castle's past.

Beckett, however, is not impressed by this new (sexy!) lady, with the police detective demanding in the preview: “What the hell is going on here?”

And you know she can’t be thrilled when she finds out Castle and Turner were close enough for Castle to base a book character around her. A little too close for comfort, to say the least.

Castle, Beckett and Turner pursue a ruthless killer who isn’t just a murderer, but is also part of a sinister, international conspiracy. “This is just like being in a Jason Bourne movie,” Castle says gleefully (before he gets flung around the front seat of a car).

Castle’s daughter, Alexis also makes an appearance at the crime scene, sporting a “Medical Examiner” on her jacket. It’s for her internship, she explains, hoping that shadowing Dr. Parrish will help her application for med school.

Castle, however, is clearly none-too-thrilled about sharing “his” crime scenes with his daughter.

And though he can be petulant and childish, his reaction this time might be warranted – the crime scene his daughter witnesees involves a victim who fell out of a fourth floor window, who was not only shot with bullets, stabbed and choked, but also ended up with a pencil jammed inside of his neck.

“Overkill” indeed…

The first part of the Jennifer Beals episode on “Castle” airs Monday, Feb. 13 at 10pm ET/PT on CTV Two.
